The 550: Your country is not allowed to connect to this server error in cPanel/Exim means that the server is blocking emails from specific countries. To fix this issue, follow these steps:
🛠 Steps to Fix Email Bounce Back Issue in Exim (cPanel)
1️⃣ Edit the Exim Configuration File
Open the Exim configuration file:
nano /etc/exim.conf
2️⃣ Find the Country Restriction Rule
Look for a section that includes:
drop message = Your country is not allowed to connect to this server. log_message = Country is banned hosts = +blocked_incoming_email_country_ips
3️⃣ Comment Out or Remove the Restriction
Modify it by commenting out or removing the block:
# drop # message = Your country is not allowed to connect to this server. # log_message = Country is banned # hosts = +blocked_incoming_email_country_ips
4️⃣ Save the File
For nano, press:
📌 `CTRL + X` → Press `Y` → Press `Enter`
For vi/vim, press:
📌 `Esc` → Type `:wq` → Press `Enter`
5️⃣ Restart Exim
Apply the changes by restarting Exim:
systemctl restart exim
✅ Alternative Fix: Check cPanel WHM Settings
If the issue persists, check cPanel WHM settings:
1. Log in to WHM.
2. Go to Home → Security Center → Country Blocking.
3. If country blocking is enabled, remove restrictions for the country in question.
4. Save changes and restart Exim.
🔍 Additional Debugging
If the issue persists, check the Exim logs for blocked emails:
tail -f /var/log/exim_mainlog | grep "Your country is not allowed"
If necessary, whitelist the sender’s **IP** in Exim:
echo "yahoo.com : ACCEPT" >> /etc/exim.whitelist
Then restart Exim:
systemctl restart exim
🚀 Summary
✔ Edit Exim config to remove country-based email restrictions.
✔ Restart Exim to apply changes.
✔ Check WHM Country Blocking settings (if using cPanel/WHM).
✔ Review Exim logs for further troubleshooting.
